The easy way to optimum measurement
results in all flow velocity ranges.
In order for air conditioning and
ventilation systems to run smoothly and efficiently, the flow velocity in the
ventilation duct must be regularly checked. Only when the flows in the duct
correspond to the requirement are the room loads (heat, cold and substance
load) reliably transported away – and the indoor air quality is right.
If the ventilation duct is accessible, duct
measurement is then the best solution. This is because air flows are measured
most accurately directly in the duct. However, it must be taken into account
that the flows in the duct are usually non-homogenous and turbulent.
In order to obtain reliable results in
spite of this, measurements should always be taken at several points over the
duct cross-section. In these grid measurements, the mean flow velocity is
calculated from the individual measurement values.
Ventilation measuring instruments from
Testo support you in grid measurement just as reliably as in the automatic
calculation of volume flow.
Which instrument suits your application
depends on the flow velocity range you wish to measure.
